PEDESTAL'FOR ARTICLES OF FURNITURE, SUCH AS MOUNTED CHAIRS, TABLES,

AND THE LIKE Albert Stoll, Koblenz, Switzerland Application February 18, 1932, Serial No. 593,844, and, in Germany February 26', 1931 J This invention relates to pedestals for articles 11 and the socket 12 res'pectivelybyanut13 screwed of furniture, such as mounted. chairs, tables and on a threaded portion of the bushing 6, whereby the like; it is the object of the invention to prothe legs 8 are rigidly connected to the tube 1. vide a pedestal which permits an adjustment in In order to adjust the height of theseat above 5 height, as well as, a turning of the seat or table the floor an adjusting device is inserted in the 60 and a resilient support of the-latter. The pedinner tube 2' comprising a pivotal operating hanestal according to the invention comprises an dle 18' and a flexible cable 19 connecting said outer verticaltubular member to which a foot handle with a plunger 1'7, displaceably arranged member is connected and in whicha supporting in an enlarged portion of the bore of the inner l0 shaft for the furniture portion is supported, the tube 2'.

of the metal legs 8. For securing the legs 8 to the tube 1, to the outer surface of the latter short sleeves 15 provided with off-standing ears 14 are secured between which the legs 8 are inserted and held fast by wood screws, as shown. Preferaby the sleeves 15 are connected to the metal tube 1 by welding, but when it is desired to arrange the legs in removable manner on the tube, for example for purposes of transport, the lower sleeve may be secured to the tube by means of cotter pins or the like.

The invention provides considerable improvements in the construction of a pedestal for articles of furniture, such as chairs, tables and the like in as much as a pedestal is obtained which permits an adjustment in height, a turning of the seat or table and a resilient support for the weight to be carried by the pedestal. All the elements, which are necessary for these functions of the pedestal are hidden for the greatest part in an outer tube, whereby a more pleasing aspect of the chair and the like and a better protection of the parts against dust and wear is obtained.

Furthermore, the construction according to the invention is advantageous in the respect that upon the removal of a screw 16 securing a cap on top of the member in position, the supporting shaft as well as all the relevant parts inside said member can be demounted, thus enabling exchanging any part when it is worn.

I claim:

1. In a pedestal for articles of furniture, such as mounted chairs tables and the like, in combi nation, an upstanding tubular member, a foot member fixed to said tubular member, a supporting shaft for the upper furniture portions, said supporting shaft consisting of two parts axially displaceable relatively to each other for height adjustment, means to lock said two parts in their adjusted position, bearing means' mounted in said tubular member for turnably holding said supporting shaft, and spring means interposed between said tubular member and said supporting shaft for resiliently mounting the latter, said supporting shaft, locking means, bearing means and spring means being arranged within said tubular member.

2. In a pedestal for articles of furniture, such as mounted chairs, tables and the like, in combination, an upstanding tubular member, a foot member fixed to said tubular member, a support ing shaft for the upper furniture, said supporting shaft consisting of two telescoping tubes axially displaceable relatively to each other for height adjustment, means .to lock said two tubes in their adjusted positions, a neck bearing mounted in the upper part of said tubular member for turnably holding said shaft and a ball thrust bearing arranged in the lower part of said tubular member for supporting said shaft, and spring means interposed between the outer of the shaft tubes and said thrust bearing for resiliently mounting said shaft, said supporting shaft, locking means, bearing means and spring means being arranged within said tubular member.
